I have been in the same boat. I have no friends, but a wife and kid. Life sucks a big one, especially work and the work-life balance, and finances, etc.
The only thing that helps me is medicine. I'm on a cocktail of Dextroamphetamine for ADD, Lamotrigine for Bipolar Disorder, and Propranolol for anxiety. I'm still far from 100%, but I'm in the more positive side of the fence.
Talking about problems can help a lot of people, and that's great to have a therapist, but it doesn't work for me. Talking about stuff doesn't change my circumstances, neither does my mindset. Definitely discuss issues with a doctor and medicate. Nothing else has helped me deal with the shit in life.
